The piston pumps are one of the most important components in the field of hydraulic engineering. These devices are used to convert mechanical energy into fluid energy, playing a crucial role in a wide range of industrial applications.
In this article, we will provide a comprehensive guide on piston pumps, we will examine how they work and list the best ones currently on the market.
A piston pump is a mechanical device used to move liquids or fluids by harnessing the reciprocating motion of pistons. These pistons move within a cylinder, creating positive pressure and generating a continuous flow of liquid. Piston pumps are commonly used in various industrial applications, thanks to their ability to handle high pressures and offer precise flow control.
A piston pump is made up of several fundamental parts:
The operation of a piston pump is based on the cycle of suction and pumping of the fluid. During the suction phase, the drive shaft moves the connecting rods, advancing the pistons towards the pumping chamber and creating a vacuum in the suction chamber. The intake valves open, allowing the fluid to enter the pump to fill this vacuum.
As the pistons move towards the pumping chamber during the pumping phase, the intake valves close to prevent the fluid from returning. Conversely, the exhaust valves open, allowing the fluid to be expelled from the pumping chamber and directed to the desired location.
This alternating movement of the pistons continues cyclically, allowing the pump to keep transferring fluid efficiently and continuously.
The piston pumps, thanks to their immense versatility in handling a wide range of fluids, are widely used in numerous industrial applications.
They can be employed in sectors such as the petrochemical industry, where they are used for the production, transport, and refining of oil and gas. Moreover, piston pumps are extensively used in the chemical sector for the transfer of fluids, precise dosing, and mixing of products.
In the mining industry, these pumps are used for pumping liquids and sludges during extraction. Within the automotive field, piston pumps are found in internal combustion engines for the movement of coolant and engine oil.
These are just a few examples of their applications; their usage can vary based on the specific needs of each sector.
We at Emiltec market piston pumps specifically designed for use with water, ideal for applications mainly related to washing.
The cost of piston pumps varies significantly based on various factors such as flow capacity, operating pressure, the quality of construction materials, the brand and model of the pump, as well as the availability of additional features and options.
Generally, piston pumps with low capacity and pressure start at a few hundred euros. The more performance-oriented or high-pressure pumps can reach several thousand euros.
It is essential to consider that a high-quality piston pump represents a long-term investment, as it guarantees reliability and longevity.
